Serena Williams Blows off Steam in New Twerking Video Before Dazzling at Documentary Premiere

After posting her famous twerking video on Snapchat in April, Serena Williams is back at it again, this time shaking her muscular glutes in a skirt she designed before stepping out at the debut of her new documentary.

The tennis pro shared her latest booty popping clip on Instagram yesterday, wearing a fringe skirt from her Serena’s Signature Statement collection in the color deep plum. She is seen opening a window and dancing to Travis Scott’s “Antidote” as her assistant Grant Firestone sits in the background. Williams seemed to be blowing off steam ahead of the premiere of her new Epix film Serena later that night.

At the premiere of the documentary in the SVA Theatre in New York City, Williams switched her hair from loose curls to a sleek and straight look and wore a gold high split down with spaghetti straps and a cleavage-baring neckline. Matching gold earrings and a necklace completed the outfit along with a watch and strappy beige heels.

The 21-time Grand Slam title holder’s TV film will provide an intimate look into her personal and professional life. According to a press release, viewers will be able to see William’s candid interactions with family and friends along with colleagues and competitors. The doc will showcase the pressures the athlete faced trying to reach a “Serena Slam” – four Grand Slam wins in a row – and losses at 2015 U.S. Open and 2016 Australian Open.

“2015 was a defining time in my life and career,” Williams said in the press release. “I think my story will be relatable to audiences whether you love tennis or not. It’s a story of perseverance, failure and triumph. It’s the most intimate I’ve ever allowed myself to be on film. It was a scary but ultimately really gratifying experience, which I’m hoping inspires others to pursue their dreams. I’m really grateful to Epix for this incredible opportunity and the care they’ve shown me. Can’t wait for you all to see it.”
